Dog Uni - you know it makes sense!
Besides - they don't tend to ask too much in the oral part.
Favourite's are:
1.What instruments and elec driven and what are vacuum driven?
2.What instrumens use Pitot and static sources?
3.How many fuel tank drain points are there?
4. Speeds: Rotate, Best Climb Rate, Best angle, Approach, Stall clean and dirty,
5.Max TOW
6.Fuel tank capacity - of which useable?
7. Type of engine?
8. Max speed with canapy slightly open?
Shouldn't take too long to look them up and commit to memory - besides the initial instrument questions are the same for most light aircraft - so a quick look in Trevor Thom or such should sort those out.
Best of luck!
